ROM Directory
|
2017-03-22 16:53:43 +00:00
|
|
|
======================
|
|
|
|
|
napple1 contain basic.rom and monitor.rom files on
|
|
|
|
|
the ./rom directory. However, If you want to put
|
|
|
|
|
basic.rom and monitor.rom on another directory.
|
|
|
|
|
Please use ROMDIR environmental variable.
|
|
|
|
|
|
|
|
|
|
For example, if you want to put basic.rom and monitor.rom
|
|
|
|
|
on current directory, the command is:
|
|
|
|
|
|
|
|
|
|
ROMDIR=. ./napple1
|
|
|
|
|
|
|
|
|
|
Default value of the ROMDIR is ./rom
|
|
|
|
|
You can use an absolute path for the ROM Directory.
|
|
|
|
|
|
|
|
|
|
ROMDIR=/home/username/my_rom_files ./napple1

How to use programs on napple1

- Key map

|
|
|
|
|
|
|
|
In normal terminals, if you press 'D' key, it will be echoed as 'd' on screen.
|
|
|
|
|
And press 'Shift + D' prints 'D' on screen. Shift key works to flip caps.
|
|
|
|
|
|
|
|
|
|
However, napple1, if you press 'D' key, it will be echoed 'D'. All letters
|
|
|
|
|
you can type is upper case only. Because original apple1 has a limit to do so.
|
|
|
|
|
And shift key works like a control key in napple1.
